Extent of disability following traumatic extremity amputation.

Extremity amputation is a devastating injury. Forty-two patients who sustained traumatic limb amputation were contacted 3-57 months (mean, 25 months; median, 24 months) after injury to evaluate residual disability and to determine what factors were associated with a good recovery. There were 35 men and 7 women with ages ranging from 5 to 73 years (mean, 34 years). Amputation was the result of a motor vehicle crash in 18, work-related injury in 11, motorcycle crash in 9, and other causes in 4. There were 46 amputations done: 8 above-knee (AK), 25 below-knee (BK), 5 above-elbow (AE), and 9 below-elbow (BE). Twenty patients reported no problems with their prosthesis, 8 had major (e.g., infections) and 6 had minor (e.g., skin breakdown) problems. Eight patients did not receive or did not use a prosthesis. Fourteen patients were discharged to an inpatient rehabilitation facility, 25 to home with outpatient rehabilitation, and 3 had no rehabilitation. Of those who worked before their injury, only 50% returned to work. The mean and median time to return to work were 14 and 12 months, respectively. Three of five full-time students returned to school. The amputation level in patients returning to work or school was BK in 12, BE in 3, and AE in 1. No patient with a AK amputation and only 1 (9%) patient with a work-related injury returned to work. Associated injuries or inpatient rehabilitation did not correlate with returning to work. Eighty-eight percent of patients were satisfied with their adjustment and could perform all activities of daily living.(ABSTRACT TRUNCATED AT 250 WORDS)

Innervated dorsal adipofascial turnover flap for fingertip amputations.

Traumatic or thermal injury to the fingertip may result in composite tissue loss. Exposed tendon, bone, or joint surface is best treated by flap coverage. The authors present their experience with a new technique that provides coverage for fingertip defects using the innervated dorsal adipofascial turnover flap, which consists of adipofascial tissue only and relies on the arterial anastomotic network of this tissue layer to sustain its vascularization. Eight digital amputations between the distal phalanx proximal to the nail matrix and midportion of the middle phalanx were resurfaced successfully with the innervated dorsal adipofascial turnover flap. The flaps survived completely; the mean follow-up was 9 months. This technique seems to be a relatively simple way of achieving early recovery. It does not require the use of distant flap immobilization of adjacent digits, nor does it require the use of homodigital flaps, which may jeopardize an already injured finger. The main advantages of the innervated dorsal adipofascial turnover flap are its ready availability from the local tissue, its sensation, and the absence of functional and aesthetic disturbance at the donor site.

Lower limb landmine injuries.

The medical records of 186 patients seeking treatment for landmine injuries in the authors' region between 1993 and 2001 were evaluated. Of these patients 13 died of accompanying complications. Ten (10) patients with general body trauma and upper limb trauma were excluded from the study. Of 163 patients with lower-limb injuries included in the study, 21 with traumatic amputation underwent surgical amputation at different levels. Patients without traumatic amputation were divided into 2 groups. There were 41 patients (29%) in Group I who were treated by limb salvage procedures. Treatments used in Group I including wound debridement, tendon repair, skin approximation, minimal osteosynthesis, external fixation of long bones and secondary wound coverage. In Group II, there were 101 patients (71%) with primary amputation. Trans-tibial amputation was performed in 52 cases (51.4%), ankle disarticulation in 24 (23.7%), trans-femoral amputation in 9 (8.9%), partial foot amputation in 8 (7.9%), knee disarticulation in 7 (6.9%) and hip disarticulation in 1 case. In Group I, there was infection in 21 patients (51.2%), revision in 27 (65.8%), and amputation in 15 (36.5%). In Group II, there was infection in 28 patients (27.7%), revision in 17 (16.8%), and amputation at a higher level in 8 (7%). In crush injuries such as those resulting from landmines, soft tissue, vascular, and neurological assessment must be performed with utmost care. Even so, the desired success in interventions intended to save a limb is complicated by a high infection rate, soft tissue complications, and high revision amputation rates. Therefore, a decision to amputate in the early term based on an accurate preoperative assessment is crucial.

Free-flap salvage of a traumatic below-knee amputation.

A traumatic below-knee amputation with extensive soft-tissue loss and tibial bone exposure was salvaged by employing microsurgical free-tissue transfer to obtain stable soft-tissue coverage. The free flap covering the bony stump and knee function have done well with over 1 year follow-up.

Calcaneal fillet flap: a new osteocutaneous free tissue transfer for emergency salvage of traumatic below-knee amputation stumps.

Traumatic below-knee amputations do not always leave enough soft tissue of bone with which to fashion a stump of sufficient length and durability to support a prosthesis. Composite free flaps can often be harvested from the amputated limb to provide immediate one-stage stump salvage and to preserve knee function. We report a new technique to increase stump length by incorporating the calcaneus into a foot fillet flap as a vascularized bone transfer. The calcaneal fillet flap is a useful addition to the inventory of available composite flaps. It is recommended for knee joint salvage when there is less than 11 cm of tibial remnant length.

Traumatic forearm amputation with avulsions of the ulnar and median nerves from the brachial plexus.

A case of a traumatic forearm amputation and associated complete avulsions of the ulnar and median nerves from the brachial plexus due to a crush-traction injury of the distal part of the right forearm is reported. The patient also suffered a traumatic head injury. The injury of the upper limb and the general condition of the patient were so serious that an amputation at the 1/3 middle part of the forearm had to be performed.

Chopart prosthesis and semirigid foot orthosis in traumatic forefoot amputation. Comparative gait analysis.

Gait was analyzed in seven otherwise healthy males at least 11 mo after they had recovered from a traumatic unilateral transmetatarsal amputation incurred during the course of their usual occupation. All seven were fitted with a semirigid foot orthosis. Four were also fitted with a Chopart prosthesis. Gait was evaluated with forceplate measurements of ground reaction force during free walking, by clinical observation of such ambulation on videotape, and by the subjective impression of the men as obtained by a questionnaire. In all men, with unmodified footwear, with the orthosis, and with the prosthesis, the forceplate data showed an abnormal pattern characterized by reduced stance duration and deficient forward propulsion on the amputated side. The abnormality and asymmetry of ground-reaction forces were less with greater preserved stump length and for a given stump length were with the above-ankle concept (Chopart) prosthesis than with the below-ankle concept. These features were recognized during the clinical analysis of all footwear, but there was an extra irregularity of weight progression noted with the fixed ankle of the Chopart prosthesis. The questionnaire reported stump problems to be the principal difficulty, and the follow-up revealed persistent attempts at surgical management including consideration of amputation at a higher level. It was concluded that the patient and the surgeons are likely to choose preservation of limb length over considerations of function during acute care and that the prosthetic concept best suited to deal with the resulting stump should emphasize unloading the distal part of the stump and smoothing out the impulsive force peak on the stump in late stance to minimize pain and to enhance ambulation capacity.

One hundred sixty-seven thumb replantations and revascularisations: early microvascular results.

One hundred sixty-seven thumb replantations and revascularisations were performed from 1977 to 1987 by the Ljubljana microsurgical team. Early microvascular results of thumb replantations and early reoperations were analysed retrospectively. Age of the patients, level of traumatic amputation, mechanism of injury, use of arterial grafts, severity (total-subtotal) of amputation and occurrence of thrombosis were potential survival factors analysed with logistic regression analysis. The overall success rate for this series was 66% (72% for failures to revascularise excluded). The most frequent cause of failure was venous thrombosis. The most critical time for failure was the first 4 days after the replantation. No microvascular complication occurred later than the seventh day and no reoperation was successful later than the third day after replantation. Survival factors were studied with logistic regression analysis which showed that the model was not statistically significant. However, estimation of relative risks gave us useful but statistically uncertain information regarding the survival factors inspected.

Complete ear replantation without venous anastomosis.

Traumatic amputation of the entire auricle is a rare occurrence. Management ideally consists of microvascular reconstruction of auricular arterial, venous, and nerve continuity. However, appropriately sized veins are often not available and venous drainage must be accomplished with leech therapy. In occasional cases where leeches are unavailable or cannot be made to attach, mechanical drainage and anticoagulation can give satisfactory drainage. The authors present a case of mechanical wick venous drainage of a complete ear replantation, resulting in virtually normal appearance and function of the ear. In addition, the ear regained normal touch and two-point sensibility, although the great auricular nerve had not been repaired.

Modified great toe wrap for thumb reconstruction.

Reconstruction of the traumatically amputated thumb can be achieved with good cosmetic and functional results utilizing autogenous bone graft and a neurosensory free wrap-around flap from the great toe. The donor area of the toe is modified to create a wrap-around flap to transfer innervated glabrous skin from the medial and lateral borders of the toe. This modification includes nail and nail matrix while preserving toe length and the important plantar weight-bearing skin of the great toe. A series of three patients who have undergone thumb reconstruction utilizing this method are reported. Postoperative follow-up averages 15 months. Sensory recovery is comparable to that reported in the literature; cosmetic appearance of the thumb and nail growth are good.

Emergency knee joint salvage utilizing a free musculofasciocutaneous flap based on the anterior tibial artery: case report.

A young adult male presented with a traumatic amputation at the upper third of his left leg and an extensive soft tissue loss around his left knee. A free musculofasciocutaneous flap was elevated on the anterolateral part of the amputated segment and transferred to the soft tissue defect around the proximal left tibia in order to avoid an above-knee amputation. The entire flap depends on the anterior tibial artery for its blood supply. The anatomy of the flap is outlined. The importance of the musculocutaneous blood supply as well as the presence of an extensive fascial component make the flap very reliable. An 18-month follow-up period showed a uniformly well-contoured soft tissue coverage and an optimal functional result.

Microvascular anastomoses in replanted fingers: do they stay open?

Replantation of fingers is a well established procedure following traumatic amputation. Several studies have documented the functional results of replanted digits. Studies have not documented the long-term (greater than 5 yrs) patency of the microvascular anastomosis in the replanted digit. Duplex imaging, a combination of B-mode ultrasound and bidirectional Doppler ultrasound has been shown to visualize vessels 1 mm in diameter. Color enhancement of the ultrasound image is now possible. We evaluated 18 patients with 24 replanted fingers to assess vascular patency. A minimum of five years follow-up was required for inclusion in the study group. Examination showed a patent anastomosis in every case and a Digital-Brachial Index within normal limits in 71% of the digits. Microvascular anastomoses in vessels as small as 1 mm in diameter remain open as long as 11 years following completion. The sophisticated techniques of color enhanced Duplex imaging makes long-term evaluation of these procedures possible in a non-invasive and accurate fashion. The use of such imaging modalities will have an important role in the evaluation of replanted digits and microvascular procedures in general.

Digital replantation in children: a long-term follow-up study.

This paper reports a series of 14 cases of digital replantation in children who had had a total of 17 digits traumatically amputated. All but two digits survived, for an overall success rate of 88%. The length of follow-up was between 3 and 14 years (average 8 years). Sensory recovery of all digits was satisfactory. The mean growth rate of replanted digits relative to contralateral digits was 86%. Twelve cases had an excellent result, and one case had a good result. Digital replantation in children is recommended when feasible.

Island skin flap with neurovascular pedicle from the dorsum of the index finger for reconstruction of the thumb.

This paper describes the successful reconstruction of badly injured thumbs in nineteen patients with transposition of a neurovascular pedicle island flap from the dorsum of the index finger. The flap has a consistent arterial supply (the first metacarpal artery), good sized veins, and terminal branches of the superficial radial nerve. Five patients had either palmar, dorsal, or circumferential loss of soft tissue from the thumb. Twelve patients had acute traumatic amputations requiring distal thumb reconstruction, and two patients had distal amputations with late reconstruction. In both immediate and late reconstruction, we maintained length and skin coverage with good circulation and sensation. This one-stage operation requires less postoperative care than many other procedures currently in use and may be employed in a wider variety of cases.

Radiological appearances following limb replantation: a report of 5 cases.

Plain radiographs of the limbs were reviewed after replantation procedures following traumatic amputation in 5 patients at the wrist (2), mid-forearm (2) and knee (1). Following upper limb replantation, rapid development of osteopaenia was initially noted in the juxta-articular regions and metaphyses of the tubular bones of the hand. These changes were followed by diaphyseal cortical bone loss with evidence of subperiosteal, intracortical and endosteal bone resorption. Juxta-articular erosions developed at the margins of the small joints in the hand in all cases. Gradual resolution of bone changes was noted in 3 of the 4 cases where follow-up exceeded 5 years. Following lower limb replantation, there was no evidence of bone loss; however, severe neuropathic joint disease developed within 18 months and progressed over the following 9 years. We suggest that the radiographic changes observed after upper limb replantation reflect regional hyperaemia secondary to neurovascular damage, whilst the changes in the lower limb reflect a similar process in a limb subjected to weight bearing.

Replantation of the upper extremity in children.

Since Malt and McKhann performed the first successful replantation of a traumatically amputated extremity in 1962, there has been a flurry of case reports and articles debating the pros and cons of the various technical aspects of replantation. There have been three case reports of children, under the age of 15, who have successfully undergone replantation of the upper extremity transected throught the humerus. The first case report in this article is the fourth. The factors involved in selecting replantation or amputation, and the technical aspects of the operation which are felt to be important, are briefly reviewed. Because the mechanics of limb replantation are rather straightforward, we feel that the pediatric surgeon should be familar with the preoperative and intraoperative factors to be weight, and that this alternative to stump closure be carefully considered when one is presented with an upper extremity transection.

Total thumb reconstruction by an index finger transposition.

A case of total thumb reconstruction after traumatic amputation is described. The reconstruction was carried out as a staged procedure with preliminary application of a pedicle flap, and a normal index finger transposition, followed by opposition transfer using the abductor digiti quinti muscle. Twenty-seven months after the index finger pollicization, the reconstructed thumb had satisfactory function.

Unexpected reorganization of somatosensory cortex in a raccoon with extensive forelimb loss.

Electrophysiological recordings were made from primary somatosensory cortex in a raccoon that had suffered a traumatic amputation of the forearm some time prior to its capture. Neurons in the affected forepaw region of sensory cortex were not silent but responded to cutaneous or neuroma activation of the remaining forearm stump. In addition, cells at many sites were responsive to tactile stimulation of the glabrous skin of the hindpaw ipsilateral to the damage. This indicates that the cortical plasticity following peripheral nerve damage can occur over much larger regions of cortex than was previously thought. An unmasking of silent thalamocortical terminals is not likely to be the mechanism underlying this plasticity in the raccoon.
